Angelo Henderson, a Pulitzer Prize-winning journalist, radio talk show host and community leader, died Feb. 15 in Pontiac, Mich. He was 51.

Oakland County Medical Examiner’s Office spokesman Bill Mullan said Mr. Henderson died of natural causes, but no other details were available.

Mr. Henderson, most recently a host on Detroit radio station WCHB, previously worked for the Detroit News and the Wall Street Journal, where he won the Pulitzer Prize in 1999 in the feature writing category for a portrait of a druggist driven to violence by encounters with armed robbers.

Mr. Henderson interviewed the druggist and his colleagues and spent a year researching the life of the man the druggist killed.

Mr. Henderson helped found Detroit 300, a citizen-based, crime-fighting organization that patrolled neighborhoods and encouraged cooperation with the police. The group was dissolved in 2012 after two of its members were killed.

Mr. Henderson also was an ordained minister.

Chad Kellogg

mountain climber

Chad Kellogg, an elite alpinist who climbed some of the world’s highest and most challenging peaks, died Feb. 14 while descending Mount Fitz Roy, a prominent peak in the Patagonia region of Argentina. He was 42.

Mr. Kellogg, of Seattle, and his climbing partner, Jens Holsten, had successfully reached the summit of the 11,000-foot mountain and were hanging together from a pre-established anchor when a rock fell, striking Mr. Kellogg and killing him.

No attempts will be made to recover his body.

Mr. Kellogg turned to climbing after his goal of becoming an Olympic luge racer ended. He once held the record for the fastest ascent-descent of Mount Rainier — a climb he had made numerous times — finishing in just less than five hours.

Mr. Kellogg had amassed an impressive record, scaling many previously unclimbed mountains in remote parts of the world. He still holds the record for the fastest round-trip climb of Denali’s West Buttress route in Alaska at 23 hours 55 minutes.

He attempted three times to break the speed record for climbing Mount Everest, the world’s highest mountain, but never reached the summit. He had planned to try again next year.

In 2007, Mr. Kellogg’s wife, Lara Bitenieks Kellogg, died in a fall from Mount Wake in Alaska’s Denali National Park.

Horst Rechelbacher

beauty-products CompanY FOUNDER

Horst Rechelbacher, who was the founder of Aveda, a beauty-products company, died Feb. 15 at his home in Osceola, Wis. He was 72.

His company posted a notice on its Web site. The St. Paul Pioneer Press reported that Mr. Rechelbacher was diagnosed with pancreatic cancer in 2011.

Mr. Rechelbacher was an Austrian immigrant who founded the Minneapolis-based company in 1978. He started with one salon before turning it into a larger company that sells hair- and skin-care products for men and women.

He eventually sold his company to the Estee Lauder conglomerate for $300 million.

George Robert Hall

Vietnam prisoner of war

George Robert Hall, a retired Air Force colonel who spent more than seven years in captivity as a prisoner of war in North Vietnam, died Feb. 16 in Hattiesburg, Miss. He was 83.

He had Parkinson’s disease, his brother Sam Hall said.

Col. Hall was shot down over North Vietnam in 1965 during a reconnaissance mission. He spent much of his captivity in the infamous “Hanoi Hilton” prison before he was released in 1973.

In 2005, he and his wife co-wrote “Commitment to Honor,” a memoir of his POW experience.
